First of all, I'm not just asking this because I'm looking for a way to run roms. I have <9.2, so I can use CFW anyway. But I thought of two methods in which it might be possible to run "backups". I noticed that HANS is capable of redirecting both the code and the romfs for a game to the SD card. So what if you tell HANS to load one game in this way, but have the code and romfs for a different game on the SD card? Wouldn't it just overwrite the whole thing with the new game, letting you play it? The second way depends on when exactly the system checks signatures. Basically, since HANS bypasses the normal process of launching a game (which enables region free, among other things) I'm thinking it might let you run installed CIA's without needing a signature patch. As for actually installing the CIA's, we already know it's possible to load the eShop through HANS, and obviously that has the necessary access to install CIA's. So you could replace it with modified code that can load CIA's from the SD card, maybe even a completely different program, like FBI or DevMenu. Would either of these work? I'm assuming I'm probably wrong about something, considering if it worked, someone would probably have already figured it out. But there's always the chance that I'm the first to think of it, and even if it doesn't work, I'm still curious why it wouldn't, so I thought I'd post it here anyway.
